The invention relates to lifting and handling devices, can be used for loading and unloading operations, for assembly operations, turning, transporting goods.

The purpose of the invention is to increase the ease of operation, reduce the time for construction and increase the labor productivity of loading and unloading.

1 shows a device with a load, a general view; figure 2 - wedge support element; on fig.Z - the same, top view; figure 4 is a view of And figure 2; on fig.Z - section bb In figure 2; Figure 6 shows the slinging of cargo using two wedge elements (for carrying cargo in the vertical position).

The load gripping device (FIGS. 1-5) consists of a sling 1 and a support element, which is a wedge support element 2 with an inclined surface 3 and a surface 4 mounted on the load 5. The wedge support element 2 is made from a smaller height on the side Through holes 6 and 8 with holes 6, one (7) of which is mated with hole 6 at the apex of the support element, is located parallel to its inclined surface, and the second one (8) is made at its base. Sling 1 extends into slot 7 in such a way that branches 9 of sling 1 are on opposite sides of wedge support member 2, and coils of sling are formed on inclined surface 3. A wedge support element 2 is fitted with safety latches 10, preventing the outburst of the sling from the slits 7 and 8. On the wedge support element 2, elastic support elements 11 and 12 are installed, which serve to prevent and wedge the wedge support element from the load during installation. Safety latches and support elements are made of an elastic material, such as rubber. In order to lift and transport the cargo in a vertical position (Fig.6), the mouth

Two wedge bearing members 2 are poured in opposite sides of the load. They are spaced apart in height, and in the loops of the branches 9 lines 1 passes an additional line 13,

the ends 14 of which are threaded into the loops of each of the two lines 1 and put on the hook 15, the middle part 16 of the additional line 13 is also thrown over the crane hook.

Load handling device operates as follows.

The two-looped sling is inserted into the slot 7 of the wedge support member - the one where the turns of the sling are formed, and is fixed with safety latches 10. Then the sling is inserted into the slot 8, where it is fixed by locking elements 12, while the branches 9 of the sling must be on opposite sides of the wedge support an element which, with turns formed around it, is looped on the hook 15 of a crane or other lifting mechanism.

In order to grip the load, the turns of the sling 1 are placed on the surface of the load, the wedge support element 2 is mounted on the load by the support elements 11 and 12 (surface 4). In the process of lifting, tension arises in the branch x 9 of the sling, selection of the slack of the sling 1 takes place, tightening of the wedge support element 2 under the turns of the sling, then further lifting and transporting the cargo to its destination. The operations of spraying and removing the device from the load are performed in the reverse order.

If it is necessary to install and transport cargo without deviating from the vertical position, on the opposite lateral sides of cargo 5, two wedge support elements 2 are installed at different heights. An additional sling 13 is threaded into the loops of the branches 9 on which one of the wedge support elements is suspended, and its end 14 is thrown onto the hook 15, after which the middle part 16 of the sling 13 is thrown onto the hook 15, then the other end 14 of the additional sling 13 is passed through the end The legs of branches 8 and 9, on which another wedge support element hangs, after which the end 14 of the additional sling 13 is thrown onto the hook 15.

When lifting the load 5, the slacks of the slings 1 and 13 are selected, the wedges are tightened, and as a result of the addition of the additional sling 13 along the hook 15, the forces in the slings are redistributed until the load is in a vertical position

(up to equality of effort in the branches of the sling 13).

The use of this device allows us to improve serviceability during lifting and transport operations, simplify and speed up the labor-intensive operation of loading cargo, reduce the time of the working cycle of lifting and transport operations, which makes it possible to increase the productivity of loading and unloading.

In addition, the device allows the installation and transportation of goods without deviating from the vertical position, which is required in many cases during assembly works, when carrying out
